Review outlines neonatal high-frequency jet ventilation practice
A narrative review summarizes high-frequency jet ventilation (HFJV) for neonatal respiratory failure, including its mechanisms, parameter setting and use in complex lung conditions. The authors describe potential advantages over other modes but note that clinical practice has developed largely without a strong evidence base.

High-frequency jet ventilation (HFJV) has been used for neonatal respiratory failure for more than 35 years, primarily in North America and often as rescue therapy. This narrative review summarizes its mechanisms, practical parameter setting and use in the neonatal intensive care unit; it does not report a new patient cohort or comparative trial. The authors discuss use in pulmonary hypoplasia, severe pulmonary interstitial emphysema, congenital lung disease, evolving bronchopulmonary dysplasia and gas trapping.
HFJV delivers rapid, pressure-limited pulses alongside positive end-expiratory pressure supplied by a separate ventilator. Compared with high-frequency oscillatory ventilation, it allows passive expiration and independent adjustment of inspiratory time and rate. These features may permit lower mean airway pressures and longer expiration, but the review describes these as theoretical advantages rather than established outcome benefits.
The authors emphasize that appropriate settings must be matched to the infant’s lung mechanics and end-expiratory needs. They also warn that HFJV can cause harm if used inappropriately; endotracheal tube position and adequate PEEP are important considerations. The review notes that practice has evolved largely through experience, with a limited preclinical and clinical evidence base, and identifies knowledge gaps requiring further research.
In practice
The review offers clinicians caring for neonates a practical overview of HFJV use in complex respiratory conditions, including pulmonary hypoplasia, interstitial emphysema and gas trapping. It describes how passive expiration and independent adjustment of inspiratory time and rate may be useful in selected lung mechanics, but these are theoretical advantages, not demonstrated comparative outcome benefits. HFJV remains a modality with a limited clinical evidence base; the review stresses individualized settings, correct endotracheal tube position and adequate PEEP, and does not establish that practice should change.
